Fed September Rate Hike Odds Surge Past 85 Percent

Market-implied odds for a Federal Reserve interest rate hike at the September 15-16 meeting rose above 85 percent. This increase followed the release of August core Consumer Price Index data that exceeded economist forecasts. The probability had been approximately 70 percent prior to the data release. Investors are now also pricing in a higher likelihood of a second rate increase by December.

Core CPI rose 0.3 percent month over month in August. This figure confirmed that inflationary pressures remain elevated despite five years of policy efforts. The Federal Reserve has left rates unchanged at five meetings this year. However, internal dissent is growing, with three voting members supporting a 25-basis-point increase in July.

Persistent Inflation Drivers

A record increase in wireless phone service prices contributed significantly to the August inflation rise. While this may be a one-off factor, other pressures are more persistent. Brent crude oil climbed to 109 dollars per barrel on Thursday. Higher energy costs are expected to feed into transportation and production costs.

Strong economic demand is also sustaining price pressures. This demand is partly driven by the rapid expansion of data center infrastructure. Unemployment remains low and stable. Some Federal Reserve officials now believe current interest levels are restraining demand less than previously assumed.

Policy Credibility At Stake

Federal Reserve Chair Kevin Warsh has stated that core inflation has not improved sufficiently. He indicated the central bank must act unless evidence shows inflation is moving back to the 2 percent target. Leaving rates unchanged could be seen as inconsistent with these prior statements. Bloomberg Economics notes that failing to deliver a hike could weaken the Chair's position.

Economists at TD Bank and JPMorgan revised their forecasts after the data release. They point to a higher likelihood of monetary policy tightening. The market reaction was swift, with futures contracts reflecting the shift in expectations. The central bank faces pressure to align its actions with its communicated policy stance.

Market Reaction And Outlook

According to GN markets/policy (en-US), the shift in probability is driven by both data and institutional signals. The U.S. economy remains strong enough to support tighter monetary policy. Political tensions between the Federal Reserve and the administration may intensify if rates rise further. The market now clearly expects action at the upcoming September meeting.
